技術原理

　　表皮或內(nèi)皮細胞之間通過緊密連接形成一層具選擇性的細胞屏障，細胞屏障不僅控制鄰近細胞間間隙對各種溶解物的擴散滲透率，而且調(diào)控跨細胞物質(zhì)轉(zhuǎn)運。細胞屏障的存在一方面保護了機體免受有害物質(zhì)的傷害，另一方面也限制了治療性藥物的進入。

　　細胞屏障的通透性可以通過跨膜電阻（即TEER，Transepithelial resistance)來反映，細胞屏障的通透性與跨膜電阻TEER之間的關系為：通透性越高TEER越低，反之亦然。

應用案例

　　■  用跨膜電阻（TEER）值法檢測Caco-2細胞屏障的完整性應用案例 

　　用跨膜電阻（TEER）值法檢測Caco-2細胞屏障的完整性。Caco-2細胞以5×10³細胞/孔的密度接種于Transwell小室中。周每隔更換一次新鮮培養(yǎng)基，然后在接下來的兩周每天更換一次新鮮培養(yǎng)基。并使用NanoAnalytics公司 Cellzscope2軟件對所得實時數(shù)據(jù)進行分析。

　　Caco-2細胞培養(yǎng)19天后，細胞跨膜電阻值≥500 Ω·cm²，細胞形成一個完整的單層屏障，完整性通過Lucifer Yellow滲透性測試得到進一步得到證實，進而單層細胞屏障可用于下一步的運輸實驗。SRL和SRL NCs的細胞毒性呈濃度依賴性（圖1B）。SRL和SRL-NCs的半數(shù)大抑菌濃度分別為147.51μg/mL和165.41μg/mL。在50μg/mL的SRL和SRL-NCs作用72h后，細胞存活率保持在80%以上。這表明本研究中使用的SRL濃度不會引起顯著的細胞毒性。因此，藥物對細胞活力的影響可以忽略不計。

　　轉(zhuǎn)運實驗采用完整緊密連接的腸上皮Caco-2細胞單層作為模型，SRL和SRL-NCs組的跨膜電阻（TEER）值（圖1D）在整個轉(zhuǎn)運過程中未顯示出任何顯著變化，表明在沒有緊密連接遭到破壞的情況下，Caco-2細胞單層的完整性得以維持。

　　將含藥物HBSS緩沖液和空白HBSS緩沖液分別添加到模型頂層（AP）和基底外側(cè)（BL）側(cè)，模擬藥物從GIT到血液的吸收和轉(zhuǎn)運途徑。也就是說，細胞層從GIT中運出藥物并將其輸送到血液/腸系膜淋巴。相反，當將藥物HBSS緩沖液添加到BL側(cè)和空白HBSS緩沖液添加到AP側(cè)時，模擬了動物血液進入腸腔的過程。計算出SRL-NCs的流出速率由于Papp、BL-AP/Papp、AP-BL與SRL顯著不同（圖1C）。原因可能是藥物被納米化后藥物變得更小，比表面積增加，因此跨單層的轉(zhuǎn)運顯著增強。另一種可能是細胞占據(jù)了整個SRL-NCs結構，因此與SRL組相比，通透性增強，SRL-NCs組AP→BL側(cè)Papp高5.6倍，外排率低。

數(shù)據(jù)測試

1.細胞屏障的特性

　　cellZscope可以連續(xù)監(jiān)測細胞幾天甚至幾星期的生理狀態(tài)。從cellZscope所提供的跨膜電阻值（TEER）和電容值（Ccl）這兩個參數(shù)可以獲知當前的細胞狀態(tài)，包括融合度和分化度。CaCO₂是源自人類結腸癌細胞系，通常用于藥物轉(zhuǎn)運研究，圖中cellZscope跟蹤記錄了CaCO₂細胞層的形成和分化的信息，自動化的記錄了從接種細胞開始并持續(xù)觀察21天。

長時間監(jiān)測細胞屏障的形成

2.緊密連接動力學

　　上皮細胞和內(nèi)皮細胞的跨膜阻抗值與細胞間緊密連接密切相關。緊密連接可影響細胞間物質(zhì)轉(zhuǎn)運過程。通過cellZscope測量細胞層跨膜電阻可以用于研究緊密連接動力學。圖示MDCK細胞對不同濃度的EGTA的反應。
